Compile new template style for piezoelectric.
Same for the strain tensor.
Make proper use of the strain base class.
o the same for the piezoelectric tensor.
Allow step-0 to compile.
Put in a generic tensor base class.
Add a base class for all tensors.
Include tensor_base header.
Make tensor_base aware of its order.
Switch usage of deal.II headers.
Compile strain with tensor_base.
Make global use of tensor_base.
Allow compilation of step-0.
Bug fix instantiations.
Various minor tweaks to notation and other.
Add a function to make the tensor rank public.
Sketch how to imbed the function distribute_coefficients into the relevant base class. Note, this breaks step-0.cc (nothing is distributed).
Change notation in templates order is Order.
Add a little comment.
Bug fix.
